I remember Droid-Life mentioning 3 PM as a good time to be close to their website (I'm assuming Eastern Time Zone, since the event is in NY). The after party is a extremely late. Like, extending-into-the-next-day late. I'm assuming there will be a press release earlier than that, but aside from what Droid-Life has said, who really knows when. If I remember right, there is no live streaming allowed for this event. This is definitely a....unique....type of unveiling.

EDIT: After looking around some more, I see it's not so much of an event, it's more like a series of press conferences for journalists, but no one is allowed to report what they see until an embargo is lifted, which is around 3 PM. They get a few hours to carefully write up their articles and make sure they have their information accurate before they are allowed to release the new. Sounds like a great idea to me. This way, important details hopefully aren't missed in an anxious rush to post the news. Then later, the after party.

I am extremely interested in the customization concept relative to carrier availability... so if you get a sec in Q&A and it hasn't already been addressed, you'd be my hero for gaining clarity on that.
